When releasing the SV100 GNSS receiver with RTK bridge function, some users are curious about this function. What is the RTK bridge? Why do we need it and how to use it?

For most RTK users, radio is a common method of differential data transmission with no network coverage requirements. However, due to the limited transmission range and high power consumption, most RTK receivers require an external power supply and an external radio to increase the range. Only a few can guarantee a range of 15 km with internal radio. Our Y1 GNSS receiver can make it, which benefits from the built-in LoRa module.

With the rapid development of the high precision GNSS industry, the GNSS surveys are becoming more and more popular worldwide. When selecting the GNSS products, we can see the static accuracy, RTK accuracy and PPK accuracy in the specifications. Of these common GNSS measurement methods, is the higher accuracy the better? What's the difference between these methods, and in which applications should we choose which corresponding method?

Static survey is the most basic survey method of GNSS receivers, which can achieve millimeter-level accuracy after post-processing. Surveyors should be very familiar with the RINEX data format, as it is the most common and standard raw data format for static surveys.
